BORDEN RADIO COMPANY - XTALMAN PICKARD CRYSTAL RADIO KIT - BUILD A PICKARD CRYSTAL RADIO!! Greenleaf Whittier Pickard invented the crystal detector in 1906. This crystal set kit was named after him in his honor. The original Pickard Crystal Set Radio Kit was designed for a Rice University class on Amateur Radio for eight-to-twelve year olds that was presented at the Houston, Texas, Museum of Natural Science. This is an improved version of that kit. High quality parts are used throughout. The pre-drilled routed base board is made from clear furniture grade pine that can be stained for an attractive vintage look. The pre-punched coil form is made from heavy cardboard shipping tubing like the Uncle Al's crystal sets of the 1920s. This material will stand up to practically anything imaginable. A solid spring brass rod is used for the tuning slider. It will not bend or loose its tension. A black flaired knob has been added to contribute to the vintage appearance. The 1N34A Germanium crystal detector is hand selected and tested for greatest sensitivity. Nickel plated brass fahnestock clips are used for all connections. A current path resistor is used for the earphone for best volume and fidelity. A ceramic capacitor in the tuning circuit provides great selectivity for a slider tuned crystal set. A sensitive ceramic earphone is included read more
